Foot & Ankle Conditions We Treat in Brighton, MI
Your feet and ankles are incredibly complex structures that take on the full impact of everything you do — walking, running, standing, working. When something goes wrong, it affects everything. At Brighton Foot & Ankle, Dr. Castelein and Dr. Tinawi treat a comprehensive range of foot and ankle conditions for patients throughout Livingston County and the surrounding communities. Whether you’re dealing with something common like heel pain or a more complex issue that requires surgical care, our team has the expertise and experience to help.
We believe in treating the whole patient, not just the condition. That means taking the time to understand your symptoms, your lifestyle, and your goals before developing a treatment plan. Most conditions can be resolved without surgery — but when surgery is the right path, you can trust that Dr. Castelein is one of the most experienced podiatric surgeons in the region. Browse our full list of conditions below or call us today to get started.
Conditions
The Achilles tendon connects your calf muscle to your heel bone and is one of the most commonly injured tendons in the body. We treat everything from mild tendonitis to complete ruptures using both conservative and surgical approaches.
Ankle fractures range from minor stress fractures to complex breaks involving multiple bones. Brighton Foot & Ankle has in-office X-ray for same-visit diagnosis and offers both conservative and surgical treatment depending on severity.
Ankle sprains are one of the most common injuries we see and one of the most commonly undertreated. Left unaddressed, a sprained ankle can lead to chronic instability. Dr. Castelein offers expert evaluation and treatment including the Brostrom procedure for recurring sprains.
Ankle tendonitis is inflammation of one or more tendons surrounding the ankle joint, often mistaken for a sprain. Early treatment is key to preventing it from becoming a chronic condition. We offer conservative and surgical options tailored to which tendon is affected.
Arthritis causes progressive joint damage that can significantly limit mobility and quality of life. Dr. Castelein offers a full range of treatment options from conservative care and PRP injections to joint replacement and fusion surgery.
A bunion is a bony deformity at the base of the big toe that worsens over time without treatment. Brighton Foot & Ankle offers multiple surgical and non-surgical bunion treatment options in Brighton, MI to relieve pain and correct the underlying deformity.
Dermatological Foot Conditions
Skin and nail conditions like athlete’s foot, fungal toenails, corns, calluses, and skin cancer of the foot are all treated at Brighton Foot & Ankle. Many of these conditions are highly treatable when caught early.
Diabetic Foot & Ankle Conditions
People with diabetes face unique and serious risks when it comes to foot health. Dr. Castelein provides comprehensive diabetic foot care including annual exams, neuropathy management, ulcer treatment, Charcot foot care, and diabetic footwear.
Flat feet can cause pain in the feet, ankles, knees, and even the lower back. We diagnose and treat flat feet with custom orthotics, physical therapy, and surgical reconstruction for more advanced cases.
Foot fractures are among the most common injuries we treat. Brighton Foot & Ankle has in-office X-ray for fast same-visit diagnosis and offers conservative and surgical care for all types of foot fractures including stress fractures and metatarsal breaks.
A hammertoe is a deformity of the second, third, fourth, or fifth toe that causes an abnormal bend in the middle joint. Treatment options range from conservative measures and in-office tenotomy to surgical correction depending on severity.
Heel pain is one of the most common reasons patients visit a podiatrist. It can stem from several conditions including plantar fasciitis, Achilles tendonitis, heel spurs, and stress fractures. Dr. Castelein identifies the root cause and builds a treatment plan around it.
Ingrown toenails are painful but very treatable. Most cases are resolved in a single visit at Brighton Foot & Ankle. For recurring ingrown toenails, Dr. Castelein offers a permanent solution through a simple in-office procedure.
A neuroma is a thickening of nerve tissue between the toes that causes burning, tingling, and the sensation of a pebble in your shoe. We treat neuromas with orthotics, injections, and surgery when conservative options haven’t provided relief.
Peroneal tendonitis is a common cause of outer ankle pain that is often mistaken for an ankle sprain. The peroneal tendons stabilize the ankle during movement and can become inflamed from overuse or injury. Early treatment prevents it from becoming a chronic problem.
Plantar fasciitis is the most common cause of heel pain, affecting millions of people each year. That sharp pain with your first steps in the morning is a classic sign. 90% of patients find relief without surgery through Dr. Castelein’s conservative treatment approach.
Plantar warts are caused by HPV entering the skin through small cuts on the bottom of the foot. Brighton Foot & Ankle offers fast effective foot wart removal in Brighton, MI using salicylic acid, cantharidin, and surgical excision.
From ankle sprains and stress fractures to turf toe and tendon injuries, Dr. Castelein treats a full range of foot and ankle sports injuries. Our goal is always to get you back to the activities you love as quickly and safely as possible.
A stress fracture is a small crack in the bone caused by repetitive force and overuse. Common in runners and athletes, stress fractures in the foot most often affect the metatarsal bones and can worsen significantly if left untreated.
Traumatic injuries to the foot and ankle including fractures, dislocations, lacerations, burns, and crush injuries require prompt expert care. Dr. Castelein has extensive experience managing complex traumatic foot and ankle injuries.
Toenail fungus causes nails to thicken, discolor, and become brittle over time. It is highly common and notoriously difficult to treat without professional care. Dr. Castelein offers topical, oral, and laser treatment options to clear the infection and prevent it from coming back.
Foot and ankle wounds that aren’t healing properly can quickly become serious, especially for patients with diabetes or compromised circulation. Brighton Foot & Ankle offers advanced wound care including debridement, biologics, and infection management.

My first visit with Dr. Castelein and his staff were exceedingly productive. The office was run so efficiently, and great pains were taken to get me in for an appointment. Dr. Castelein and his assistant were beyond friendly and knowledgeable. I left with hope that my very flat feet and stretched tendons can be managed and I will be able to get back to walking again without pain soon. Thank you everyone!Posted on Google![]()
